My understanding is that there are people with immune system disorders for whom vaccines are either less effective or are ineffective.
That means that if they come in contact with a carrier, they aren’t really immune PLUS if they catch the disease it poses a significantly higher health risk. The only way to protect them is to protect all the kids around them.
That being said, I don’t believe in forcing parents to vaccinate their kids. I DO support denying those kids access to many public facilities (including schools), as well as giving private citizens and organizations complete latitude to demand proof of vaccination and to deny service or entry to those who either refuse to provide it or don’t meet predetermined standards.
You know full well that'll never fly. Gonna make that hold for the illegal alien invaders' kids from over the border?
Can't do it.
Because it's RAAAAASSSSSIST....
